Question

The class marks distribution are 105,115. Determine class interval

Answer 1

I think the class interval should be 10.

Because when the class is 100-110

The class mark is 105.

And when the class is 110-120

The class mark is 115.

So the class interval is 10.

HOPE THIS MAY HELP YOU...

Answer 2

CLASS INTERVAL IS 10
